On April 22, 2010, CenturyLink announced it would acquire Qwest in a 0.1664 shares of CenturyLink common stock for each share of Qwest common stock transaction.[2] The merger closed on April 1, 2011. Qwest began doing business as CenturyLink in August 2011.[3]

Qwest provided voice, Internet backbone data services, and digital television in some areas. It operated in three segments: Wireline Services, Wireless Services, and Other Services. The Wireline Services segment provided local voice, long distance voice, and data and Internet (DSL) services to consumers, businesses, and wholesale customers, as well as access services to wholesale customers. The Wireless Services segment was achieved by a partnership with Verizon Wireless. Qwest also partnered with DirecTV to provide digital television service to its customers. In Phoenix, Denver, Salt Lake City, Boise, and Omaha, Qwest offered Qwest Choice TV. The Other Services segment primarily involved the sublease of real estate assets, such as space in office buildings, warehouses, and other properties.

Qwest Communications also provided long-distance services and broadband data, as well as voice and video communications globally. The company sold its products and services to small businesses, governmental entities, and public and private educational institutions through various channels, including direct-sales marketing, telemarketing, arrangements with third-party agents, company’s Web site, and partnership relations. As of September 13, 2005, Qwest had 98 retail stores in 14 states. Qwest Communications was headquartered in Denver, Colorado at 1801 California Street, in the second tallest building in Denver at 53 stories. The majority of Qwest occupational or non-management employees are represented by two labor unions; the Communications Workers of America and in Montana, the International Brotherhood of Electrical Workers. Qwest also had software development centers in Bangalore and Noida (New Delhi), India called Qwest Software Services.

Founded in 1996 by Philip Anschutz, Qwest began in an unconventional way. Anschutz, who owned the Southern Pacific Railroad at the time, established the subsidiary Southern Pacific Telecommunications Company and began installing the first[where?][citation needed] all-digital, fiber-optic infrastructure along his railroad lines and connecting them into central junctions in strategic locations to serve businesses with high-speed data and T1 services. In 1997, the Southern Pacific Railroad was merged into the Union Pacific, in which Qwest gained access to UP's railroad lines to lay fiber-optic cable for its telecom network. At that time Anschutz had a contract with MCI to lay nationwide fiber for them along the railway lines; he took advantage of this situation and laid his own fiber along with that of MCI. In 1995, SP Telecom moved from San Francisco to Denver after acquiring Dallas-based Qwest Communications Corp., a digital microwave system owner, taking over its name and facilities. The Qwest headquarters were at 555 17th Street.

Qwest Communications grew aggressively, acquiring internet service provider SuperNet in 1997, followed by the acquisition of LCI, a low cost long distance carrier (located in Dublin, Ohio and McLean, Virginia) in 1998, and followed again by the acquisition of Icon CMT, a web hosting provider, also in 1998. This launched Qwest as not only a provider of high speed data to the niche market of corporate customers, but also a quick-growing residential and business long distance customer base that it quickly merged into its data service.

Qwest partnered with the Dutch national telecom operator KPN to create the pan-European data communications and hosting company KPNQwest. KPNQwest was formed in November 1998 and went on to launch an Initial Public Offering on the Nasdaq and Amsterdam stock Exchanges in November 1999. KPNQwest collapsed in bankruptcy in 2002.

Qwest merged with "Baby Bell" US West on June 30, 2000 through an apparent hostile takeover. Philip Anschutz owned 17.5% of the resulting company. Unlike prior merger transactions between the Baby Bells, in which the acquired entities survived as subsidiaries of SBC Communications and Bell Atlantic, US WEST ceased to exist when it was immediately absorbed into Qwest with all subsidiaries of US WEST becoming directly owned by Qwest.

As a condition of the merger, Qwest was required to sell off its long distance operations in the 14-state boundary in which it provided local telephone services. They were eventually sold to Touch America. In 2003, Qwest acquired Touch America from 360networks after Touch America filed for bankruptcy. The acquisition ended ongoing disputes between the two companies in which Touch America alleged Qwest continued to illegally sell long distance services within the former U S WEST region.[4]

In 2002, Qwest agreed to sell its directory operations, QwestDex, to private equity firms The Carlyle Group and Welsh, Carson, Anderson & Stowe for $7 billion. The sale allowed Qwest to generate cash to fend off a bankruptcy filing that it may have had to resort to due to significant amounts of debt it had incurred since the collapse of the dot-com bubble.[5] The resulting company was named Dex Media.

Qwest Communication partnered with other major communications companies, including AT&T and Verizon, to form Movearoo.com.[6] Created on July 9, 2008, the website is a program designed to help customers in the process of moving find home service providers available in their area.[7]

One of the historically significant mass complaints regarding Qwest involved allegations that the then-long-distance-only company switched local telephone service customers over to Qwest's long-distance service without their permission, an illegal practice known as slamming. In July 2000, Qwest paid a $1.5 million fine to the Federal Communications Commission to resolve slamming complaints. In April 2001, they paid a $350,000 fine to the Pennsylvania Bureau of Consumer Protection after the state cited them for deceptive advertising and slamming practices.[8] The company's settlements included a requirement that all of its sales employees sign a pledge stating that slamming was barred and a condition for dismissal from Qwest employment.

The company was also involved in accounting scandals, and was fined $250 million by the U.S. Securities and Exchange Commission (SEC), to be split into two $125 million payments due to the poor state of Qwest's current financial health. Among the transactions in question were a series of deals from 1999 to 2001 with Enron's broadband division which may have helped Enron conceal losses. In 2005, former Chairman and chief executive officer (CEO) Joseph Nacchio, former President and chief operating officer (COO) Afshin Mohebbi and seven other former Qwest employees were accused of fraud in a civil lawsuit filed by the SEC. Separately, Nacchio was convicted of 19 counts of insider trading in Qwest stock on April 19, 2007.[9] On March 31, 2011 US Federal Judge Marcia Krieger issued a summary judgement rejecting all SEC's claims against Afshin Mohebbi and ruling in his favor.

Qwest's original slogan was "Ride The Light", which was meant to portray the company as technologically advanced. In 2002, Richard C. Notebaert, who took over as CEO that year, introduced the "Spirit of Service" campaign which promotes the company as being refocused on customer satisfaction.

In the case of ACLU v. NSA, U.S. District Judge Anna Diggs Taylor on August 17, 2006 ruled that the government's domestic eavesdropping program is unconstitutional and ordered it ended immediately.[12] The Bush Administration filed an appeal in the case, and Judge Taylor's decision was overturned by the appeals court.

Former Qwest CEO Joseph Nacchio, alleged in appeal documents that the NSA requested that Qwest participate in its wiretapping program more than six months before September 11, 2001. Nacchio recalls the meeting as occurring on February 27, 2001. Nacchio further claims that the NSA cancelled a lucrative contract with Qwest as a result of Qwest's refusal to participate in the wiretapping program.[13] Nacchio surrendered April 14, 2009 to a federal prison camp in Schuylkill, Pennsylvania to begin serving a six-year sentence for the insider trading conviction. The United States Supreme Court denied bail pending appeal the same day.[14][15]

On April 22, 2010, CenturyLink announced it would acquire Qwest in a 0.1664 shares of CenturyLink common stock for each share of Qwest common stock transaction. CenturyLink shareholders will hold a 50.5% share of ownership in the combined company, while Qwest shareholders would own the remaining 49.5%. The valuation of CenturyLink's purchase as of April 21, 2010 is $22.4 billion, including the assumption of $11.8 billion of outstanding debt held by Qwest as of December 31, 2009.[26][27] Qwest has started to do business as CenturyLink from August 8, 2011.

Qwest Communications International, Inc. was the holding company. It is the parent company of many more entities, but those listed below are the main operating units:

Qwest Corporation is an incumbent local exchange carrier (ILEC), and since it was part of the AT&T Bell Operating System as Mountain Bell, it is also a Bell Operating Company.

It was the classic pre U S WEST merger entity founded in 1966 as Southern Pacific Telecommunications Company. Qwest Communications Corporation changed its name and corporate status on January 2, 2009, to a limited liability company.
